In pins: Pin, Discover and Share Resources

standard metadata is useful

List of 10
 $ file       : chr "df.rds"
 $ file_size  : int 200
 $ pin_hash   : chr "db696042be80dbb4"
 $ type       : chr "arrow"
 $ title      : chr "title"
 $ description: NULL
 $ tags       : NULL
 $ urls       : NULL
 $ created    : chr "<TODAY>"
 $ api_version: int 1

newer version triggers error

Metadata requires pins 2.0.0 or greater
i Do you need to upgrade the pins package?

produces reasonable default title

Code
  default_title("name", path = c("data.csv"))
Output
  [1] "name: a pinned .csv file"
Code
  default_title("name", path = c("data.csv", "foo.csv"))
Output
  [1] "name: 2 pinned files"
Code
  default_title("name", data = mtcars)
Output
  [1] "name: a pinned 32 x 11 data frame"
Code
  default_title("name", data = 1:10)
Output
  [1] "name: a pinned integer vector"
